Demonstrations and Posters -------------------------- ER2003 provides a forum for ongoing work: poster reports on projects in progress, demonstrations of alpha- and beta-versions of software tools and products, invitations to cooperate on new project ideas, etc. These should stimulate a highly interactive and future-oriented added value to ER2003. Please send poster and demonstration proposals to the Demonstration and Poster Chair, Heinrich C. Mayr (mayr@ifit.uni-klu.ac.at) by 20 June 2003.
